Kernmaster static line from Yale Cordage has a unique design for static rappelling construction. Kernmaster™ utilizes a 48-strand solution dyed polyester braided cover (mantle), but deviates from the standard or historical parallel, bundled core construction of nylon. The core employs a steam-stabilized, braided nylon core which maximizes energy absorption, eliminates in-field hardening, enhances working flexibility and minimizes core fiber fatigue.
